...k these are good principles because they makes types simpler to understand and to implement. Method dispatch for `vec_c()` is quite simple because associativity and commutativity mean that we can determine the output type only by considering a pair of inputs at a time. To this end, vctrs provides `vec_type2()` which takes two inputs and returns their common type (represented as zero length vector): str(vec_type2(integer(), double())) #> num(0) str(vec_type2(factor("a"), factor("b"))) #> Factor w/ 2 levels "a","b": # NB: not all typ...

You can read more about `vec_size()` and `vec_type()` at <https://vctrs.r-lib.org/articles/type-size.html>. ## Stability The definitions of size and prototype are motivated by my experiences doing code review.
